Purchases made through auction sites, marketplaces, private or third-party sales, or other unauthorized online retailers are not eligible for warranty.

    This warranty does not apply to: (i) any other costs, including costs of removal, installation, diagnostic time, and any other expenses arising out of replacing the product (ii) products which have been installed on non-catalogued applications; (iii) products that are new, unused or show signs of normal wear but not defective; (iv) products which have been misused, modified, altered, improperly applied or installed; (v) product damaged in an accident or by fire, weather, or any other force majeure event or hazard; (vi) products which have been installed on vehicles used for commercial, fleet, Governmental or racing purposes or damaged due to vehicle modifications; (vii) obsolete parts no longer available from DRiV; (viii) product that has been transferred from the vehicle on which it was originally installed; (ix) non-geniune DRiV branded product or competitive parts; and (x) products installed on vehicles that have been modified outside the specifications of the vehicle’s original equipment manufacturer, including but not limited to aftermarket modifications for racing, off-road, or powersports purposes.

    DRiV will not accept any returns and is not responsible for any claims related to circumstances and products described in the preceding sentence. All warranties, express or implied, are disclaimed if not stated herein. Any implied warranties you may have under state law are limited to the same duration and other terms as this warranty to the extent permissible.
